Abstract
Starting from 3,6-dichloro-4-pyridazinecarboxylic acid chloride a series of novel pyridazino[3,4- b][1,5]benzoxazepin-5(6 H)-ones as 1,2-diazine isosters of nonnucleoside reverse transcriptase inhibitors was prepared via N-(2-hydroxyphenyl)-3,6-dichloro-4-pyridazinecarboxamides. The inhibition of HIV-1 reverse transcriptase was evaluated.

Abstract
Starting from 3,6-dichloro-N-(2-chloro-5-nitrophenyl)-pyridazine-4-carboxamide (7) a series of 6,11-dialkylated pyridazino- [3,4-b][1,5]benzodiazepin-5-ones with a 3-chloro-8-nitro, 8-amino, 8-acetylamino, or 8-chloro substitution pattern was prepared via N-alkyl-3-alkylamino-6-chloro-N-(2-chloro-5-nitrophenyl) -pyridazine-4-carboxamides. The new compounds were screened as non-nucleoside reverse transcriptase inhibitors. The influence of the substitution pattern in compounds 10-13 on inhibitory potency is discussed.
